Abstract: According to examples, a computing system may include a processor and a memory on which is stored machine-readable instructions that when executed by the processor, cause the processor to use an optical propagation model and perceptual loss function to match an output of a spatial light modulator (SLM) based holographic display to that of a target image, wherein an input illumination into the SLM includes three simultaneous human-visible wavelengths of light. Through the simultaneous input of three human-visible wavelengths of light into a common SLM, the need for spatial or temporal multiplexing of three colors may be eliminated, which may improve a display's viability in terms of form factor and/or refresh rate.

Abstract: According to examples, an image capture device may include a lens array including lenses supported by a lens support structure, in which the lenses are arranged to capture light rays from multiple view-points. The image capture device may also include a sensor to capture light and convert the captured light into data that is used to form an image and a plurality of apertures positioned between the lenses and the sensor, in which the apertures are positioned with respect to the lenses and the sensor to allow rays of light that would have reached a certain reference location spaced from the sensor to pass through the plurality of apertures. An optimization algorithm may be applied to the collected sensor data to reproduce an image of a scene at a perspective that is intended to match a virtual eye position that is offset from the location of the sensor.

Abstract: In one embodiment, a computing device may determine a virtual content to be displayed with a scene of a real-world environment. The device may generate an image depicting the virtual content. Using one or more sensors, the device may detect characteristics of the scene of the real-world environment. Based on the image and the characteristics of the scene, the device may determine that a visual enhancement is to be applied to the virtual content depicted in the image to enhance a contrast between the depicted virtual content and the scene. The device may generate a visually-enhanced image depicting the virtual content by applying the visual enhancement to the virtual content depicted in the image. The device may display the visually-enhanced image of the virtual content on a display of the computing device, wherein the scene of the real-world environment is visible through the display.

The photochromic composition includes a combination of a first photochromic material and a second photochromic material having different steady-state absorption profiles. In a direction from a first portion to a second portion of the photochromic element, a concentration of the first photochromic material in the combination decreases and a concentration of the second photochromic material in the combination increases.

Abstract: A configurable occluder/dimmer for a near-eye display includes an array of polarization rotators and a polarization-selective scatterer downstream of the array of polarization rotators. The array of rotators and the polarization-selective scatterer are disposed between a pair of polarizers. The polarization-selective scatterer only scatters light at one of two orthogonal polarizations, thereby enhancing the achieved extinction ratio of the configurable occluder/dimmer. The configurable occluder/dimmer may be used in the near-eye display to provide occlusion effects rendering added virtual objects opaque, and/or to equalize contrast of the generated virtual imagery across the field of view of the display.
